Filler



OSCAR F. CARLSON, OF CHICAGO, ILLINOIS.

FILLER.

To all whom 'it may concern: Y

Be it lmown that I, OSCAR CARLSON,

a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have. invented a certain new and useful Improvement in Fillers, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings,

and the like.

this application. Y

My invention relates to a filler for tanks The object of the present invention is to provide an improved filler for fuel tanks and the like.

While the invention ,is particularly adapted for fuel tanks of automobiles, I do not intend to limit the same to such use.

According to my invention, a filler yhead and cap are provided withregistering openings permitting the introduction of liquid into the a nipple with the tank or receptacle. The head and nipple are preferably, but not necessarily, held at an inclination to the horizontal. The .head and .caphave their registering openings preferably, but not i necessarily, cut diagonally of these two membersso as to bring the openings uppermost. The lower wallrof the head and the Y lower wall of the nipple are preferably,

' but not necessarily, continuous to provide a .smooth draining surface for the head.

The cap is tted to the head for angular as well as aXial motion', a spring being Vprovided to resist axial motion. f

The cap is provided at its lower edge -with a projection or projections and the lower end of the head is provided with a circumferential flange which has notchesdiametrically placed so that the projection i on the lower edge of the cap will automatically drop into therecesses in the flange when the cap is moved to full open or complete closed position. To move the cap from fully open or closed position, the cap is pulled out axially against the Spring and fis then rotated to permit thefcap to be brought into the desired position. When the cap is not in either fully open or fully closed position, the projection on the lower edge thereof will ride upon the flange.

lVhen the `proper position is reached, the 1 projection will automatically drop into vthe Specification of-Letters Patent.`

forming a part of head. The head is connected by n `line 4 4, looking! in the direction of the `'ieatented Nov. 25, 1919.

recess and hold the cap against further rotation. v

In order. to apprise those skilled in the art how to construct and practice my invention, I shall now describe in detail a form a part of the present case, Figure 1 is a top plan view of a filler with the cap partly broken away, the cap being in open position.

v Fig. 2 is a longitudinal axial section of `the same.

Fig. 3 is an endv view -taken from the y right of Fig'l, and

Fig. l is a transverse section taken on the arrows as shown in Fig. 1. l

The ller comprises a cylindrical head Vmember 1, having `a flat end wall 2 with a cylindrical cap 3, fitting closely around the side and end wallsl of the head l. A nipple .4f ofv suitable length is connected to the lower side of the head member 1, preferably being formed integral with the head member. The end of the nipple 4 may be vangle substantially as indicated'in FigfQ.

It willbe noted that the lower wall of the head member forms a direct` and smooth continuation of the nipple ,4 so that liquid poured into 'the head member 1 will drain directly down to the vnipple 4# without interruption or pocketing.

The head member land the cap member 8 are provided with openings which are adapted to be brought in register when the filler is-open and to be moved out of register when ,the filler is closed. For the inclinedposition in which the filler is shown, these openings are preferably cut diagonally across the uppermost corner of the head and cap, as shown in Figs. 1, 2 and 3.

A pin 5 is secured at -its outerend in the l Center of the cap member 3 and passes loosely through a hole in the end wall@ of the head.Y The iinner end of the pin 5 is provided with a head 6, between which head 6 and the end walls 2, there is placed a compression spring 7 This .spring tends at all times to Vhold the capv 3 down upon the head 1.

The lower part of the Vhead is provided with a peripheral flange 8 which has two fnotches 9 and 10 cut therein at diametrieterof the cap.

axially to disengagerthe projections 11 and cally opposite parts ofthe circumference. In the particular form illustrated, these notches are arranged at theeXtreme topand bottom, this being done for the purpose of Y' indicating the locking feature more clearly tothe user. A

The lower edge of the cap 3 has a pair r of projections. 11 andv 12, at diametrically :opposite points, adapted'to drop into the recesses or notches 9 and 10.

The cap 3 is provided with oppositely disposed horns'or handles 13 which are adapted to be engaged by the fingers of the user for pulling the cap axially against the spring'? and forrotating the cap about the head. An ornamental and strengthening flange 14 is formed onthe lower portion of the cap member particularly for strengthening the lower end of the cap between the recess and the lower edge. The placing of the projection 11 at this point also serves to strengthen this part of the cap. There isv no particular strain upon this reduced portion; first be- Y cause of the pin rwhich prevents the outer entire device being set at an angle las indicated Ain Fig. 2. The opening in the head member is turned upward and assuming that 2,-the liquid'may be poured in through the filling openings in the cap and head. When it is desired to close the opening the hooks or handles 13 .are engaged by the lingers of the operator and the cap is vpulled v'out 12 from the recesses or notches 9 and 10 in the flange'8 and the cap is then rotated. As

soon as the cap is rotated sufhciently to bring Y the projectionsk and recesses out ofregister, the projections will ride up on the'ilange 8. The cap is then turned through 180"V until snaps the projections and recesses together, holding the cap firmly closed. It is apparent the projections and recesses againcome into register; The springthen automatically that a single projection, as 11, would be sufficient to lock the capin either open or closed position. I prefer to provide two such prothe parts. are in the position shown in Fig. Y

je'ctions because of the, balancing eil'ect secured when these projections ridefup onthe edge of the flange 8.

I do not intend to be limited to the precise details of construction shown and described.-
